I think you misunderstand how cpu mining works, you need to mine using a worker created as part of a pool of miners that work together to find dash blocks of around 6 coins (forget solo mining its too difficult to find a block)
sign up to a pool then create a worker and place the worker details inside a .bat file that is part of your minerd folder.

I sometimes use xpool, you don't even need to sign upto them, you only need to put any wallet recieving address in the .bat command
